Troubleshooting
✎
If you have determined that the HID files are missing or
corrupted ("Error installing mouse" when installing the HID
dfrivers, and also a yellow "!" in Device Manager under
Mouse), check that all of the following files are present in the
\\winnt\system32\drivers folder:
◆
◆
◆
◆
Hidusb.sys
Hidclass.sys
Hidparse.sys
Mouhid.sys
If all the fi
les are there, try replacing them with the same files
from a known good system. It is suggested that you save the
original files in a backup directory.
■ The touch can not be held longer than 10 seconds.
IntelliTouch controllers have a built-in two minute untouch
time-out. By default, the 4.20 Universal driver generates an
untouch after 10 seconds of constant touch. The untouch
time-out can be changed by modifying a registry key. This
time-out will override any registry time-out value if the
registry value exceeds 120 seconds (120000 milliseconds). To
change the time-out time:
1. Run regedit or regedt32 (click Start > Run, enter regedit).
2. Drill down to HKEY_LOCAL_MACHINE > SYSTEM >
CurrentControlSet > Enum.
a. For serial controllers: SERENUM > ELOSERIAL >
******* > Device Parameters.
b. For USB controllers: HID > VID_04e7 > ******** >
***************** > Device Parameters.
The "******" entries are id numbers used by the Windows
operating system.
